The reaction of α-carbomethoxy-γ-benzylidenebutenolide with diazomethane has been studied, and the β-methylbutenolide structure of the resulting product established through degradative and synthetic work. Extension of this direct C-methylation to other related butenolides is presented. Hydrogenation of enol lactones is discussed in some detail.
研究了α-碳甲氧基-γ-亚苄基丁烯内酯与重氮甲烷的反应,并通过降解和合成方法建立了所得产物的β-甲基丁烯内酯结构。提出了将该直接的C-甲基化扩展至其他相关的丁烯内酯的方法。烯醇内酯的氢化被更详细地讨论。
